The power source 1 is an electric push rod, which is horizontally arranged on the tractor, the base of which is fixed on the upper end face of the tractor, and the push rod can be telescopically moved along the horizontal direction. In other embodiments, the power source 1 may also be an air cylinder, or a pushing device.

The first member 2 is a rod, the first end of which is connected to the power source 1 , for example, hinged, and the middle of the rod intersects and hinges with the middle of the second member 3 , and the two form an X-shape. Specifically, the top end of the electric push rod is hinged with the first end of the first member 2, and the first end of the first member 2 is driven to reciprocate in the horizontal direction by the push rod of the electric push rod.

The second member 3 is a rod, the first end of which is rotatably disposed on the tractor, for example, hinged on the upper end surface of the tractor.

The first rod 4 is vertically arranged on the tractor. Specifically, its upper and lower ends are respectively fixed on the tractor. For example, a bracket may be provided on the tractor on which the first rod 4 is arranged vertically.

The first sliding block 5 is slidably arranged on the first rod 4, the first sliding block 5 can slide up and down along the first rod 4, and the second end of the first member 2 is rotatably arranged on the first sliding block 5, for example Hinged on the side of the first slider 5 .

The first end of the second rod 6 is connected to the first sliding block 5, for example, its side surface, and the connection between the two can be hinged or welded, for example. Preferably, the second rod 6 is in a horizontal state, and its first end is vertically connected to the side surface of the first sliding block 5 .

The second slider 7 is slidably arranged on the second rod 6, the second slider 7 can move left and right along the second rod 6, and the second end of the second member 3 is rotatably arranged on the second slider 7, for example Hinged.

The ejector rod 8 is vertically slidably arranged on the tractor, for example, a vertical guide cavity can be set on the tractor, and the ejector rod 8 is arranged in the guide cavity, so that the ejector rod 8 is restricted by the guide cavity, and it can only Move vertically. The bottom end of the top rod 8 is connected with the second end of the second rod member 6, and the second end of the second rod member 6 exerts an upward or downward force on the top rod 8, thereby driving the top rod 8 to move up or down .

The tray 9 is arranged on the top end of the ejector rod 8 for supporting the vehicle. The tray 9 is generally in a horizontal state, and is used to stably support the chassis of the vehicle, so as to support the vehicle stably. The size of the tray 9 can be determined according to actual needs. For example, when the vehicle is large, the tray 9 generally has a larger supporting surface, and when the vehicle is small, a tray 9 with a smaller supporting surface can be used. The tray 9 can be welded on the top rod 8, or can be connected to the top rod 8 in a detachable manner.

When working, first move the tractor to a suitable jacking position under the chassis of the vehicle, and then drive the first end of the first member 2 to move in the horizontal direction through the power source 1, so that the first end of the first member 2 is moved towards the first end of the first member 2. The first ends of the two members 3 are close together, at this time the second end of the first member 2 drives the first slider 5 to slide along the first rod 4 , and the second end of the second member 3 drives the second slider 7 to slide along the first rod 4 . The two rods 6 slide. Since the first slider 5 restricts the second member 3 to move upward, the second rod 6 moves upward and pushes the top rod 8 to move upward, so that the tray 9 lifts the vehicle. Then the tractor pulls the vehicle to a predetermined position, such as a certain parking space, and then drives the first end of the first member 2 to move in the horizontal direction through the power source 1, so that the first end of the first member 2 is away from the second member 3, the second end of the first member 2 drives the first slider 5 to slide along the first rod 4, and the second end of the second member 3 drives the second slider 7 to slide along the second rod 6 sliding, because the first sliding block 5 restricts the second member 3 to move downward only, at this time, the second rod 6 moves downward and drives the ejector rod 8 to move downward, so that the tray 9 puts down the vehicle.

Please refer to FIG. 1 to FIG. 4 together. The self-locking device includes a base 10 , a sliding member 105 , an elastic member 106 and an electromagnet 107 .

The base 10 is arranged on the tractor, and has a self-locking hole and a slideway 104 . The self-locking hole is matched with the ejector rod 8 . Specifically, the base 10 is detachably mounted on the tractor, such as bolted, the self-locking hole is a vertical hole matched with the ejector rod 8, and the slideway 104 passes through the self-locking hole, preferably the slideway 104 is arranged horizontally.

Specifically, the base 10 includes a body member 101 and a cover member 102. The cover member 102 is detachably mounted on the body member 101. The body member 101 is provided with a self-locking groove 103 and an opening groove. The corresponding cover member 102 There is a self-locking slot 103 on it, and a self-locking hole is formed by the self-locking slot 103 on the cover member 102 and the self-locking slot 103 on the body member 101. The opening slot on the body member 101 and the cover member above it The bottom surfaces of 102 together form the slideway 104 . This structure is convenient for subsequent installation and maintenance.

The sliding member 105 is movably arranged in the slideway 104, and the sliding member 105 is a ferromagnetic material. The sliding member 105 mainly plays the role of shielding the self-locking hole and supporting the ejector rod 8 . The slider 105 can move within the slideway 104 . The sliding member 105 is preferably a sliding block. Since its upper end surface is flat, it can stably and reliably support the ejector rod 8 .

The elastic member 106 is arranged in the slideway 104 , one end of the elastic member 106 is fixedly connected to the inner wall of the slideway 104 , and the other end is connected to one end of the slide member 105 . The elastic member 106 is used for pulling the sliding member 105 back and shrinking one end in the slideway 104 when the sliding member 105 is not subject to the magnetic force, so as not to block the self-locking hole. The elastic member 106 is a return spring. In other embodiments, the elastic member 106 may also be a flexible member that can provide a return force.

The electromagnet 107 is disposed at the other end of the slideway 104 opposite to the elastic member 106 . When the power is turned on, the electromagnet 107 absorbs the sliding member 105 to move against the pulling force of the elastic member 106, and covers the self-locking hole; Self-locking hole opens.

Driven by the power source 1, the vehicle traction jacking mechanism starts to work. With the continuous extension of the electric push rod, the lower end of the jacking rod 8 gradually rises upward. When the vehicle traction jacking mechanism lifts the car, the knife can be loaded When the moving safety distance is reached, the top rod 8 moves upward along the self-locking hole to the position where its bottom end is higher than the slideway 104. After the vehicle traction jacking mechanism is stabilized for a few seconds, the electromagnet 107 is energized, and the electromagnet 107 is energized. The generated magnetic field will attract the slider 105 to move to the right and be close to the electromagnet 107, which will block the space where the ejector rod 8 falls (refer to FIG. 3). It should be noted that the slider only needs to carry the ejector rod 8. Part of the applied load, the main load has to be supported by the jacking mechanism.

When putting down the car, since the bottom of the ejector rod 8 may be in direct contact with the sliding member 105, this will hinder the movement of the sliding member 105 to a certain extent. Therefore, when the vehicle is ready to be pulled down, the vehicle is pulled up and pulled up. The mechanism first pushes the ejector rod 8 up, leaving enough space for the sliding member 105 to move, then the electromagnet 107 is powered off through the controller, and the sliding member 105 moves to the left under the elastic force of the left end elastic member 106, Then the top rod 8 falls through the slideway 104 driven by the vehicle traction jacking mechanism. When the vehicle traction jacking mechanism top rod 8 is at the lowest position (refer to FIG. 4 ), the car has been safely placed on the ground. The driver then drove the car out of the garage, and the tractor continued to serve the next vehicle.
